Question

Sove the equation for all real solutions
-d^2-12d+4=-6d^2​

Answer 1

d=25 or d=2

Explanation:

hope that helps!

Answer 2

d=2/5 or d=2

Explanation:

Step 1: Subtract -6d^2 from both sides.

−d2−12d+4−−6d2=−6d2−−6d2

5d2−12d+4=0

Step 2: Factor left side of equation.

(5d−2)(d−2)=0

Step 3: Set factors equal to 0.

5d−2=0 or d−2=0

d= 2/5 or d=2
